Insulin Needles

An insulin syringe is a medical device with a barrel, plunger, and needle used to draw insulin from a vial and inject it for diabetes management, featuring units markings for precise dosing, sharp needles for comfort, and available in different capacities (like 0.3, 0.5, 1 mL) and gauge sizes (e.g., 30G, 31G) for varying doses. They are cost-effective but require careful technique, including drawing air, injecting it, inverting the vial, and proper disposal in sharps containers. 
Key Components & Features:
  • Barrel: Contains markings (units) to measure insulin.
  • Plunger: Pushes the insulin out.
  • Needle: Made of surgical steel, often lubricated and tri-bevel cut for sharpness.
  • Gauges (G): Higher numbers (e.g., 31G) mean a thinner, less painful needle; lower numbers (e.g., 29G) are thicker.
  • Sizes (cc/mL): 0.3 mL for doses <30 units, 0.5 mL for 30-50 units, 1 mL for >50 units. 
Safety & Disposal:
  • Single-Use: Never reuse or share syringes.
  • Never Recap (After Use): Place used syringes directly into a sharps container.
  • Sharps Container: A hard plastic bottle with a screw cap or a designated sharps box.
